Biography:

Dr. Charles Wong is an expert on measuring organic contaminants in the environment, and understanding their behavior and effects on non-target organisms and their ecosystems. He received his SB and SM degrees from the Massachusetts Institute of Technology (MIT), and his PhD from the University of Minnesota, all in civil and environmental engineering. He also received postdoctoral training from the US Environmental Protection Agency and Environment Canada. Wong holds concurrent academic appointments at the University of Manitoba, the Children's Hospital Research Institute of Manitoba, and the Costa Rica Institute of Technology. He is also an Associate Editor of Environmental Pollution, an international scientific journal in the top 10% in the field of environmental sciences.

Wong has won several international awards for his research, including the Society of Environmental Toxicology and Chemistry's Weston Solutions Environmental Chemistry Award for the top environmental chemist of the year under age 40. Since joining The University of Winnipeg in 2008, he has helped to secure over $12 million in external research funding as of September 2016. His undergraduate, graduate, and postdoctoral students have to date collectively won 18 fellowships and 23 best-research-presentation awards at all local and international levels.

Research Interests:

Every day, we use personal care products and take medicines for what ails us. Our belongings are protected with flame-retardants. We cook on Teflon and use myriad other materials present in a microscopic form known as nanomaterials.

Little is known about how such substances accumulate in the environment and what their long-term effects might be. For example, when materials are reduced to nanoscale, they can exhibit radically different behaviours than in their usual, larger form.  Gold at nano scale, for instance, can be almost any color of the rainbow. Likewise, as we wash off or excrete the residues of the chemicals and pharmaceuticals we use, they enter our water systems, and ultimately the ecosystem. And we know little of how chemicals act once there. This is the world of emerging pollutants – the world of Dr. Charles Wong, Canada Research Chair in Environmental Toxicology.

Dr. Wong seeks to develop better methods for measuring chemicals at very low concentrations, to determine at what point they may become harmful, and to characterize these chemicals’ effects once released into the environment. “Understanding how to measure these chemicals, and how they behave in the environment, will lead to better ways for assessing human and ecosystem chemical exposure, and ultimately better means for guarding human and ecosystem health.”

Related to this research, Dr. Wong is pursuing the behaviour of chiral chemicals: molecules that are pairs of non-superimposable mirror images like your right and left hands. While each has similar chemical and physical properties, they may interact with other matter differently, with significant result: some common over-the-counter pain relievers are chiral chemicals, but so is thalidomide, the infamous morning sickness drug that caused thousands of birth defects. By using classic analytical chemistry, and applying environmental engineering science in both lab and field, Dr. Wong is also exploring the dynamics of chemical degradation in the body, the effects of exposure to perfluorinated chemicals in the indoor environment, and the use of engineered constructed wetlands to better remove wastewater nutrients, human and veterinary pharmaceuticals, and antibiotic resistance genes.
